Aggregation in the generalized transportation problem
(Interperiodica, 2001-11-01)
Aggregation disaggregation is used to reduce the analysis of a large generalized transportation problem to a smaller one. Bounds for the actual difference between the aggregated objective and the original optimal value are ...

Velocity‑vorticity‑pressure formulation for the Oseen problem with variable viscosity
(2021)
We propose and analyse an augmented mixed finite element method for the Oseen equations written in terms of velocity, vorticity, and pressure with non-constant viscosity and homogeneous Dirichlet boundary condition for the ...
Análise de técnicas de refino H-adaptativo em MEF utilizando estimativas de erro a posteriori em problemas de elasticidade unidimensional
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia MecânicaUTFPR, 2018-07-02)
Finding the exact solution for boundary value problems, in physical systems modeling for engineering purposes, can be complex or even imposible. Then, the Finite Element Method (FEM) is an available alternative to obtain ...
A priori and a posteriori error analyses of an HDG method for the Brinkman problem
(Elsevier, 2018-01-15)
In this paper we introduce and analyze a hybridizable discontinuous Galerkin (HDG) method for the linear Brinkman model of porous media flow in two and three dimensions and with non-homogeneous Dirichlet boundary conditions. ...
High-Order AFEM for the Laplace–Beltrami Operator: Convergence Rates
(Springer, 2016-12)
We present a new AFEM for the Laplace–Beltrami operator with arbitrary polynomial degree on parametric surfaces, which are globally W∞1 and piecewise in a suitable Besov class embedded in C1 , α with α∈ (0 , 1 ]. The idea ...
